The stoprcrelationship command stops the copy process for a Metro Mirror or Global Mirror stand-alone relationship. You can also use this command to enable write access to a consistent secondary VDisk.
Syntax
>>- svctask -- -- stoprcrelationship -- --+-----------+-- ------> '- -access -' >--+- rc_rel_id ---+------------------------------------------->< '- rc_rel_name -'
Parameters
- -access
- (Optional) Specifies that the system allow write access to a consistent secondary VDisk.
- rc_rel_id | rc_rel_name
- (Required) Specifies the ID or the name of the relationship to stop all processing for.
Description
The stoprcrelationship command applies to a stand-alone relationship. The command is rejected if it is addressed to a relationship that is part of a consistency group. You can issue this command to stop a relationship that is copying from primary to secondary VDisks.
If the relationship is in an inconsistent state, any copy operation stops and does not resume until you issue a svctask startrcrelationship command. For a relationship in the consistent_synchronized state, this command causes a consistency freeze.
When a relationship is in a consistent state – in the consistent_stopped, consistent_synchronized, or consistent_disconnected state – you can use the access parameter to enable write access to the secondary virtual disk. Table 1 provides consistency group initial and final states.
| Initial state | Final state | Notes® |
|---|---|---|
| inconsistent_stopped | inconsistent_stopped | If access is specified, the command is rejected. |
| inconsistent_copying | inconsistent_stopped | If access is specified, the command is rejected with no effect and the relationship remains in the inconsistent_copying state. |
| consistent_stopped | consistent_stopped | If access is specified, the final state is idling. |
| consistent_synchronized | consistent_stopped | If access is specified, the final state is idling. If access is not specified, the final state is consistent_stopped. |
| idling | idling | Remains in idling state whether access is specified or not. |
| idling_disconnected | unchanged | If specified without access, the relationship/group remains in idling_disconnected state. If the clusters reconnect, the relationship/group is in either inconsistent_stopped or consistent_stopped state. |
| inconsistent_disconnected | inconsistent_stopped | The command is rejected, with or without the access flag. |
| consistent_disconnected | consistent_stopped | The command is rejected if specified without access. If specified with access, the relationship/group moves to idling_disconnected. |
